PI Day 3/14

"The number π is a mathematical constant, the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. It has been represented by the Greek letter 'π' since the mid-18th century though it is also sometimes spelled out as 'pi' (/paɪ/)."

Pi fascinates humans, and has for a long, long time.

Artists celebrate it, too:

Pi also frustrates us.

For example, it's an irrational number.

We are unable to explain it as an exact, common fraction.

Darn thing never ends in decimal form - which is infinitely long.

And it never evolves into a permanent, repeating pattern.

Supercomputers calculate Pi out to billions and billions of digits.

"And they're still going." No end in sight.

One school kid memorized Pi to 10,980 digits:

The bottom line?

Although the value of Pi is just more than three, it's flat-out fascinating.
